Ok so today I was doing something a bit diffrentley than I normaly do. Instead of running sound directley from my source to the amp I had to run it though the tv to a tv out becasue of the crapy cables that my friend had with his game cube. So I had it set up to feed sound out to the amp and well it did but it was real faint so I turned the amp up and up and up and then i guess about half way up the dial it went into protection mode and shut off. The next few times i turned it on with diffrent sources it acted funny. now its back to normal but what is protection mode? And why did it occur like half way up the dial. I frequentley listen to music and have the dial up higher than that.
